CABLE-REELING MECHANISIVI.

a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new Vand useful Improvements in Cable-Reeling` Mechanisms, of which the following is a specification, reference being had therein to the accompanying drawing.

The general constructon and mode of operation of electric locomotives having cable reeling mechanisms are now well known and understood. These locomotives are used principally in mines for collecting together into trains loaded mine cars from branch entries and from various rooms in which cutting operations are being carried on. The rooms and branch entries are provided with tracks, but not with current supply wires. Therefore, when it is desired to operate a locomotive in one of the branch entries or rooms the cable reeling mechanism is used to carry and to wind and unwind a conductor cable, the free end of which is secured to a stationary electric conductor, such as a trolley wire. In this way current is carried from the stationary electric conductor to the locomotive while it is operating over tracks in the branch entries and rooms.

The object of this invention is to provide an improved means for controlling the winding of the cable rcel onto the reel, the guiding means being adapted to permit the cable being taken up or paid 'out at either end of the locomotive.

In the accompanying drawings which show the embodiment of my invention which I now deem preferable, Figure 1 is a side elevation of a locomotive having a cable guiding mechanism embodying my improvements; Fig. 2 is a plan view of the loco-motive shown in Fig. 1; Fig. 3 is a perspective view of the reel, the guiding mechanism and associated parts detached from the locomotive; Fig. 11 is a view similar to Fig. 8, with the cable extending in the opposite direction; Fig. 5 is a fragmentary cross sec tional view taken along line 5-5 of Fig. 4.

Referring to the drawings, 1 represents as a whole, an electric locomotive which may Specification of Letters Patent.

be of any of the usual forms.

t is mounted upon aXles 2 and track wheels 3, and is driven by means of motors 4.

5 is a trolley mechanism of the usual form for supplying current to the locomotive motors under normal conditions.

At one end of the locomotive is a space for the operator and at this end of the locomotive are provided t-he locomotive controllino` devices such as the controller 6. At thz other end of the locomotive is mounted the cable reeling mechanism. This mechanism comprises a reel 7 mounted to rotate about a horizontal axis. The details of construction ofthe reel and of the reel actuating` mechanism form no part of my present vention.

The construction which I have shown com` prises an electric motor 8 which is separate from and operable independently (if the main motor and of the track wheels and which has connected with it a worm 9 meshing with a worm wheel 10 rotatable on the shaft 11 of the reel. Secured to the worin wheel 10 is one element 12 of a friction clutch. The other element 13 of the clutch is splined to the shaft 11 and its movement along the shaft into and out of engagement with the clutch element 12 is controlled by means of a pivoted ring 14- connected with a bell crank 14?. This bell crank has connected with it a link 15 which extends backward and has secured to it a handle 16 within the reach of the operator. The operator, therefore, by moving the handle 16 may cause the clutch to be engaged or disengaged and the motor 8 to be connected with or disconnected from the reel.

Mounted in suitable bearings at one side of the reel and parallel to the axis thereof is a rotatable shaft 17 which is provided with double or reverselypitched cam screw threads. Atone end of the reel shaft 11 is a sprocket pinion 18 and at the corresponding end of the shaft 17 is a sprocket wheel 19. A chain 2O extends over the pinion 18 and the wheel 19 and serves to transmit power to rotate the shaft 17 at a relatively slow speed.

Mounted above the shaft 17 are two par-v allel guide bars 21, 21, which are preferably provided at their adjacent sides with longitudinal grooves.

22 is a carriage or traveler block having at opposite sides tongues 23 adapted to extend into and be guided by the grooves in the bars 21.

24 is a follower stud pivot-ally mounted in the block 22. This stud has a downward projection Vadapted to engage the walls of the threads on the shaft 17 and as the shaft is rotated to direct the traveler block backward and forward along its guide-way.

Mounted on the frame of the reel mecha- -nism at points above the ends of the shaft 17 and the guide bars`21 are two parallel upstanding brackets 25, 25. Mounted 1n these 11p-standing brackets are two parallel yhorizontal transverse shafts 26, and 27. The lower of these shafts 26 is preferably d1- rectly above the guide bars 21 and the upper of the shafts 27 iS preferably behind the= shaft 26 and nearer the vertical plane of the;` reel axis. Rotatably mounted on the shaft 26 is a cable guide sheave 28. On the shaft1 27 is a similar sheave 29. These she-aves are] so spaced by the shafts 26 and 27 that they can coperate with each other to guide the cable 35 between them. The traveler b-lock 22 carries two upward and forward extend-1 ing arms 30 and 31 which have bearings at@ 32 and 33 on the transverse shafts or barsE 26 and 27. These arms 30 and 31-are posi-f ti'oned at opposite sides of the sheaves 28; and 29 and serve to move the sheaves backward and forward along .the shafts 26 andl 27. Preferably the arms 30 and 31 carryl rollers 311 positioned in longitudinal vertical l planes at opposite sides of the sheaves 28` and 29. These rollers are adapted to guide the cable 35 as it passes between the sheaves in being wound andalso to-guide itv as it passes from the sheaves in being unwound. Preferably other rollers 36 are provided on the arms 30 and .31 for guiding the cable at a point between .the sheaves and the reel.

In operation let it be assumed that 1t is desired to pay out and take up the cable-at the forward end z'. c. at the end opposite to that at which the operato-r is positioned. The cable is passed forward in engagement with the lower sheave 28, as shown in Fig. 4, and its forward end is connected with a suitable stationary conductor. The motors 4L are then energized to drive the locomotive away from the point of attachment of the cable. During such movement of the locomotive the motor 8 may be energized or not, as the operator desires. In either case the clutch elements 12 and 13 are permitted to be in engagement and on account of friction between them resistance will be offered to the rotation of the reel in the unwinding direction. In this way a proper tension on the locomotive.

cable is insured. It will be understood of course that when the motor is not energized the worm gearing 9 and 10 will prevent r0- tation of the motor by the reel in the reverse direction. `When the movement of the locomotive away from the point of attachment of the cable has ceased and it is desired to cause the return movement of the locomotive, care is taken that the motor 8 is energized and operating whether it has been previously energized or not. As the locomotive returns the reel is rota-ted by the motor 8 in the winding direction and the cable is guided onto the reel in regular order by means of the sheaves 28 and 3l and the rollers 36 on the reciprocating guide carriage. It will be understood that the clutch interposed between the motor and the reel serves to prevent suflicient power being transmitted to unduly strain the cable. IVhen it isV desired to pay out and make up the cable from the rear or operators end of the locomotive, the cable is passed upward and backward over the sheave 29 as shown in Fig. 3, and backward over the top of the locomotive as indicated by dotted lines` in Fig. 1. Preferably a guide and support 37 is provided for the cable at a point near the rear end of the locomotive. It will be noted that the cable in this position passes through an opening 38 between the two arms 30 and 31. lith the cable in the position last referred to, the operation of the locomotive is the same as that which has been before described and the description need not therefore be repeated.

I am aware that mechanisms have been heretofore devised for permitting a cable to be paid out or taken up at either end of the So far as I am aware, however, all previous devices adapted for use with a horizontal reel have had parts which must be manually swung or shifted Vfrom one position to another.
